Also known as mica paint, the difference from metallic paint is that mica is added instead of aluminum particles. The main components of mica are iron dioxide and iron oxide. When the light hits the mica particles, it first takes on the color of iron dioxide and iron oxide, and then complex refraction and interference occur in the mica particles, so that the reflected light becomes a pearl-like flash, which is very beautiful.
三、The composition of the car paint surface from the inside to the outside:
■ Primer:
It mainly plays the role of anti-rust, directly attached to the metal plate, and generally appears off-white.
